Electric Vehicles and Sustainable Transport — Lesson 2

This lesson covers the benefits of electric vehicles (EVs) compared to other modes of transport, focusing on the potential for sustainable transport in the face of increasing global population and vehicle usage. It discusses the alarming health impacts of air pollution from internal combustion engine vehicles and the potential of EVs to reduce this. The lesson also compares different energy sources used in vehicles, including petrol, diesel, compressed natural gas, hydrogen, batteries, ultra-capacitors, and ultra-flywheels. It further explores the pollutants and greenhouse gases emitted by vehicles, their impact on health and the environment, and how EVs can help reduce these emissions. The lesson concludes with a comparison of EVs and internal combustion engine vehicles in terms of energy diversification, efficiency, capital and operating costs, and performance.
